Hum, yes but what is causing the feeling?
Is it that the eyes detect the absence of light from the point in space, compared to the surroundings?
Imagine two matrices of light values, each representing one decoded vision of the environment for one person:
56
43
26
45
(2)
34
58
78
67...
Is it not fascinating that you can feel eye contact on such distances we do?
What is it that we actually detect?
I understand that the eye absorb light, it may be the starting point for the explanation?
Thanks for your interest and time.
Well, it seems like you understood it like I did. Transmitted through 4 interfaces and reflected on the 5th, then transmitted back up to the surface through the same 4 interfaces. So would you agree on 4 times then?
Homework Statement
A seismic wave travel from surface, is reflected at the fifth of a series of horizontal interfaces. Each has a reflection coefficient "R" of 0.15. What is the total attenuation in amplitude caused by energy partitioning at all encountered interfaces, when the wave returns to...
